Desiree, Patrick R. « Synthèse et développement de macrocycles pour la capture d'anions d'intérêt thérapeutique ». Electronic Thesis or Diss., Aix-Marseille, 2022. http://www.theses.fr/2022AIXM0152.
Texte intégralSupramolecular chemistry consists of molecular architecture complex organized thanks to a combination of non-covalent interactions. At the natural state, these structures have numerous functions such as cell energy production thanks to the ATP synthase or the genetic support thanks to a polyanion, the DNA molecule. Anions can be involved in radiotherapy through iodide. By opposition, it can also be associated with environmental disasters (Fukushima explosion in 2011) or some diseases (thyroid disease). In front of these troubles, it is a priority to fight against theses disastrous events. This PhD work has focused on the construction of boronium type macrocycle able to strongly trap iodide which is an anion model to study astatide trapping. This coordination is done thanks to hydrogen bonding and ionic interactions collaboration. Based on previous works realized in our laboratory in 2010, complexation properties of Calix-carBIB were studied. In a second time, new functionalized groups were used to study their potential for different applications such as astatide purification, water solubility and vectorization. Finally, a new receptor generation was studied, showing a better affinity for astatide

Texte intégralAstatine (At, Z = 85) is a scarce halogen element, all of its isotopes being radioactive. Due to the limited available quantities, no spectroscopic tool is applicable to identify the molecular nature of At species. Consequently, the chemistry of At remains poorly known. One of its isotopes, ²¹¹At, is a potential candidate for the treatment of cancers by targeted alpha therapy. However, the limited knowledge of its chemical properties has hindered attempts to label ²¹¹At with disease targeting carrier molecules. This led to the development of a research program on the basic chemistry of At. This thesis focuses more particularly on the Pourbaix diagram of astatine and the characterization of halogen bonds with the AtI species, by means of various experimental tools (ion chromatography, competition method and electromobility). In the first part, speciation studies of At in alkaline medium confirm the presence of the At⁻ species under reducing conditions. As the potential increases, the AtO(OH)₂⁻ species is formed. The speciation change between these two species is described for the first time. In a second part, the formation of halogen bonds between the AtI species and various organic compounds was studied. The reactivity is summarized by a newly established basicity scale, with the strength between the donor (AtI) and the acceptor atom following the order of C≤ O ≤ S (≈ Se)

Texte intégralTrials to destroy cancer cells with currently synthesized 211 At-based radiotherapeutic agents are not yet fully satisfactorily since they resume to in vivo deastatination. Since this issue is related to the limited knowledge of the basic chemistry of At and its species, fundamental researches combining ultra-trace experiments and computational studies have been initiated. In this thesis, a computational study of several At species is performed, by means of relativistic density functional theory and wave-function-based calculations. First, the quantum mechanical approaches that can safely be used to make adequate predictions are established. Using these approaches, we attempt to rationalize the electronic structures, geometries, and physico-chemical properties of various systems of theoretical and/or experimental interest, in particular the AtF3 and AtO+ ones. By the end, we firmly identify a new At species by combining outcomes of experiments and calculations. This new species not only completes the Pourbaix diagram of At in aqueous and non-complexing media, but also gives clues of identifying experimental conditions to make best reactive the At– precursor, which is currently involved in the synthesis of promising radiotherapeutic agents
Guo, Ning. « Investigation of the chemical properties of astatine at +I and –I oxydation states in aqueous solution ». Thesis, Nantes, 2017. http://www.theses.fr/2017NANT4038/document.
Texte intégralTargeted alpha therapy is an appealing method for the treatment of cancer as a complement to the current approaches. Astatine-211, with a half-life of 7.21 h, is considered as an exciting prospective candidate for this application. A pre-required condition is to fix in a stable way the radioactive isotope to the vector that is going to serve to recognize cells. This asks for a thorough knowledge of the chemical properties of astatine. Considering its position in the periodic table, it can exist under the form At− in coherence with the chemical properties of the other halogens, and also possesses a more metallic character that explains the existence of stable cationic species. The objective in this work is to identify the properties of different At species in aqueous solution. The predominance of the species At− in reducing acidic conditions was confirmed by means of a technique of electromobility. A first value of absolute mobility is then proposed. In more oxidizing conditions, the species At+ dominates. The reactivity of this species with the ions of the halogens series was studied/quantified. An exotic species IAtBr− was highlighted in particular thanks to the help of modeling tools. The peculiarity of the compound AtI to form halogen-type bonds was shown for the first time

Texte intégralChampion, Julie. « Exploration du caractère métallique de l'astate en solution aqueuse ». Nantes, 2009. http://www.theses.fr/2009NANT2086.
Texte intégralAlpha-radiotherapy is an innovative technique for the treatment of cancers complementary to current approaches. The principle is to use tumor-specific vectors labeled with alpha-radioisotopes. Astatine 211 is a very promising candidate if one considers the energy of the particles emitted as well as its physical half-life (7. 2 h). One of the ways of labeling is to use astatine at a higher oxidation state as a « metal cation ». Indeed, considering its location in the periodic table, astatine is supposed to present a more metallic character than the other halogens. This way of labeling has however never been explored. This can be explained by the fact that the astatine chemistry is nearly unknown. The purpose of this work was therefore to explore this property of astatine and to define its Eh, pH diagram (or Pourbaix diagram) in non complexing aqueous solution. To this end, both experimental and theoretical approaches were used. The experimental approach uses competition methods to identify the formed species and the thermodynamics constants of studied equilibria. The theoretical approach uses methods of computational chemistry and provides information at the molecular scale on the studied systems in order to predict thermodynamic data which are used as support and complement to the experimental approach. The important result of this work shows the presence of two stable cationic forms of astatine in aqueous solution, i. E;, At+ and AtO+

Texte intégralAstatine-211 is a promising alpha emitter for the therapy of cancers. In association with a suited immunologic carrier, it could allow the treatment of some micrometastasis or residual cancer diseases. However, the lack of stability of the radiolabelling of the antibodies with this radionuclide is a limitation for the development of clinical applications. This work describes a new approach for the radiolabelling of the antibodies with astatine-211. The specificity of this method is the use for the first time of hypervalent astatine. Tin precursors were designed to allow the introduction of astatine-211 under a stabilised trivalent state. The feasibility study of the radiolabelling of the antibodies with this method and the preliminary stability assesments are also described
